Influence of Particulate Matter on Asthma Control in Adult Asthma

No clear evidence shows the association between particulate matter (PM) with an aerodynamic diameter < 10 µm (PM10) and asthma control. Therefore, objective of this study was to determine PM10 A retrospective observational conducted at Airway Clinic, Chiang Mai University Hospital, Mai, Thailand, January 2010 April 2013. Various values control test (ACT) scores high low periods were analyzed. The increased monthly average level ACT score analyzed using a time series analysis. There total 1180 visits from 236 asthmatic patients. significantly lower in period compared period. Every µg/m3 increment resulted decreased lag zero one month, adjusted coefficient –0.101 (95% CI; –0.165, –0.037), p-value = 0.002 –0.079 –0.147, –0.012), 0.021, respectively. Monthly affected During air pollution period, serial assessments should be measured for early detection worsening
